ブラウザで名前が定義されている140色をSwiftで定義する

アプリを作成する毎に、Swiftで色定義を毎回作成してはいませんか？
標準的な定義と色見本があれば、デザイナーさんやクライアントさんとの色に関するやりとりが少なくできるのではないかと考えて少しググってみました。
結果、軽く調べた感じではSwiftの定義は無くて（誰も作ってなくて）代わりに下記のような素敵なサイトを発見しました。

[原色大辞典](https://www.colordic.org)

コード書いてあるし、名前があるのが何より良いです。

色見本と言えば個人的にはPantone Colorとかかなと思っていましたが、今やブラウザーの色定義ですよ。やはり！

というわけで、出来上がったのが下記のコードです。
Appleがすでに定義しているものはコメントアウトしています。

作っているうちに、あれ？これ `#colorLiteral` の方が良くない？と思ったので、
次回作ってみます。
